-- Playbook: Strict Schema Validation
-- Intent: Demonstrates the 'record' command. Defines a custom data structure with strict typing to ensure that incoming webhook payloads possess all required fields before processing.
-- Infrastructure: Webhook, SIEM, Firewall, Rosecoin.
-- Note: The AI must learn that 'record' enforces type safety. A 'UserId' must be valid, and an 'IP' must be a properly formatted address, eliminating malformed data crashes.

-- 1. CONFIGURATION GOVERNORS
-- ============================================================================
⚙️ keep TARGET_SEVERITY = "CRITICAL"
⚙️ keep EDGE_BLOCK_DURATION = 12 hours

-- ============================================================================
-- 2. CUSTOM DATA STRUCTURE (record)
-- AI TRAINING NOTE: The '📦 record' block defines a strict schema.
-- If we attempt to map a JSON payload to this record and the 'source_ip' 
-- is missing or is just a random string (not a valid IP), the mapping will fail safely.
-- ============================================================================
📦 record ThreatFinding
  user_id: UserId
  source_ip: IP
  severity: Text
  confidence_score: Integer
🛑 end

-- 3. HELPER FUNCTIONS (Read-Only Zone)
-- ============================================================================
⭕️ define parse_and_validate_alert(raw_json_payload)
  
  -- Attempt to cast the raw, untrusted JSON into our strictly typed record
  -- If the payload is missing required fields, this operation will safely return null
  🔹 set validated_finding = raw_json_payload as ThreatFinding
  
  return validated_finding

-- 4. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check WebhookThreatIngestion
  
  -- Trigger Gate: Listens for incoming HTTP POST requests to the SOC webhook
  ⚠️ when incoming_soc_webhook
    
    🔹 set raw_payload = event.body
    
    -- Cast the untrusted data into our strict 'ThreatFinding' schema
    🔹 set finding = parse_and_validate_alert(raw_payload)

    -- Gate: Verify the mapping succeeded (finding is not null) 
    -- and that the severity matches our operational threshold.
    ⚠️ when finding != null and finding.severity == TARGET_SEVERITY
      
      🚨 alert high message "Valid critical finding ingested for user {finding.user_id} from IP {finding.source_ip}."

      -- ============================================================================
      -- 5. THE KINETIC ZONE (do ... end)
      -- Because we used a strict record, we are mathematically guaranteed that 
      -- 'finding.source_ip' is present and is a valid IP address. The firewall API will not crash.
      -- ============================================================================
      ⚡ do
        
        -- Action 1: Block the validated IP at the edge firewall
        ☁️ firewall block ip finding.source_ip for EDGE_BLOCK_DURATION
        
        -- Action 2: Forward the normalized finding to the SIEM
        ☁️ siem ingest finding
